Strobelight - LightBoost Utility for AMD/ATI and NVIDIA

Try using SoftMCCS from entechtaiwan. The setup for it will reset absolutely everything to defaults, if you go through all the steps (but one test will almost shut off the backlight). Activating a profile will reset that.

If SoftMCCS doesn't work, RMA the monitor.

After you do all this and get a proper screen, unplug and hard power cycle the monitor.
